It is very bad practice to do this: fro example what happens if you need two instances of form2 with different parameters? Rmember we get a lot of beginners reading this forum - we do not want them getting the idea that this is something you should do in the real world! Either pass parameters via the second form constructor, or use events to pass / pick up the data.
